Surgical procedures for obesity can now be safely performed by laparoscopic approach. Patients suffering from morbid obesity stand to benefit tremendously by laparoscopic surgery thus decreasing the hospital stay, minimizing pain and an early return to activity. Laparoscopic Sleeve has emerged as a highly popular and successful surgery for morbid obesity. The patient feels full after just few bites of food thus decreasing the intake and resulting in the weight loss. The procedure is safe and simple. It can be done as a short stay procedure (hospitalization for 24 to 48 hours). It is a very patient friendly procedure with tiny cuts on the abdominal wall hence an excellent cosmetic result (only few tiny puncture marks), very little pain and patient can resume his or her work within few days after surgery.

Restrictive weight loss surgery works by reducing the amount of food consumed at one time. The theory is simple; due to the restriction created, you feel satiated with small amounts of food and because of a smaller outlet, food stays in the stomach for a longer time. The net result is - a reduction in daily caloric intake without a feeling of deprivation.

Entails laparoscopic implantation of a Silastic band around the stomach just below the gastro-esophageal junction to section off a small portion called as stomach pouch creating an hour-glass effect. A small outlet, about the size of a pencil eraser, is left at the bottom of the stomach pouch.

In this procedure, stapling creates a small (15 to 20cc) stomach pouch. The remainder of the stomach is completely stapled shut and divided from the stomach pouch. It is not completely removed. The outlet from this newly formed pouch empties directly into the lower portion of the jejunum, called the Roux limb, thus eliminating the duodenum and a small portion of the jejunum from the absorptive circuit. The omitted segment is connected into the side of the Roux limb of the intestine creating the "Y" shape that gives the technique its name. The length of either segment of the intestine can be adjusted to produce lower or higher levels of malabsorption.

A procedure in which a stapling device is used to create a thin vertical sleeve of stomach about the size of a banana and the rest of the stomach is removed, thereby limiting the amount of food that can be eaten. It basically leaves a small stomach tube instead of a big stomach sack. The residual stomach capacity is about 150mls so a generous entry should be possible. Grehlin, which is an enzyme produced in the fundus of stomach, is responsible for hunger and craving for food. In this operation, Grehlin producing area of stomach is also removed, with the result that patient has satiety even after eating little bit of food and the person does not crave for food in between meals.

What Is Obesity?

Clinically, Obesity is described as the excessive accumulation of fat that exceeds the body's skeletal and physical standards. The National Institute of Health (NIH) states that excessive weight becomes a health hazard when it is 20 percent or more above ideal body weight.
Obesity becomes a serious health risk when it becomes morbid. In such cases the patient is susceptible to serious diseases like chronic heart disease, respiratory diseases or even infertility. Called co-morbidities, these conditions or diseases may result in either significant physical disability or even death. Morbid Obesity is described as having a Body Mass Index of 40 or higher.

Causes Of Obesity?

Research shows that the recent rise in obesity is due to changed lifestyles, energy-dense diets and low-levels of physical activity. However various factors may contribute to obesity which include environmental factors, heredity, psychological & cultural influences and many others. Various possible causes of obesity, as suggested by renowned doctors, are given below:

Improvements in general health are also common. Obesity-related medical conditions usually improve or even go away after weight loss surgery, including:

Diabetes

Severe arthritis

Obstructive sleep apnea

High blood pressure

About 95% of people report improved quality of life after weight loss surgery. Some studies also suggest people live longer after weight loss surgery, compared to equally obese people who do not have surgery.
